LOCOMOTIVE DRIVING BOX.

App-licationfiled November 6, 1924.

This invention relates to locomotive driving boxes and is an improvement over the construction shown in my priorP-atent No. 1,384,381, granted July 12, 1921.

An objects of the invention is the provision of a driving box employing a three quarter bearing brass which may be removed without dropping the wheels of the locomotive. y

A further object of the invention is the provision ofa driving box in which the bearing brass may be provided with a hner after the brass has reduced in size to the service. V I

A, further object-of the invention is the provision of means for locking the saddle in place.

In the accompanying drawings, I have shown one embodimentof the invention. In this showing:

Figure 1 is an end elevation of a driving box showing the use of a three quarter bearing brass formed in two sections,

Figure 2 is a vertical sectional view on line 22 of Figure 1, v

Figure 3 is a vertical sectional view on line 33 of Figure 2,

Figure 4 is a horizontal sectional view on line 4-4 of Figure 3,

Figure 5 is a View similar to Figure 1 showing a liner arranged between the driving box and the bearing brass,

Figure 6 is a perspective view of the bearing brass removed,

Figure 7 is a perspective view of the driving box removed from the locomotive frame,

Figure 8 is a similar View of the saddle, and, Figure 9 is a perspective view of the liner employed when the bearing brass becomes reduced in cross section.

Referring to the drawings, the reference numeral 1 designates a'locomotive side frame provided with the usual pedestals 2 for the reception of a driving box 3. As shown, the sides of the driving box, are provided with grooves 4 to receive the pedestal and the driving box is retained in position by means of the usual pedestal brace 5. The driving box is provided with the usual bearing receiving aperture 6 andis closed at the top as indicated at 7. The bottom portion of the driving box is open and is adapted to receive a saddle 8. As shown, the side walls of the opening are provided with tapering grooves 9 adapted to receive Serial No. 743 2'32.

ribs 10, formed on the. sides of the saddle, whereby the saddle-will be moved upwardly toward the aperture 6, as it is placed in the driving box. The front of the driving box isprovided with a pair of bolts 11, which are adapted to be received in openings 12, formed in flanges l3on the front of the saddle, which flanges are arranged in frontof the driving box when the parts are 1n aswith a rear wall 16, the upper edge of which is curved on a radius substantiallythe same as the bearing aperture 6 of the driv ng box and a lubricating well 17. is formed therein,

Suitable means are provided for locking the saddle in positionindependent of the nuts 11 and bolts 15. As shown, the front of the saddle is provided with a depending flange 18. This flange is provided with an opening 19. A locking plate 20 is. adapted to be arranged in front of this flange and the locking plateis provided with an opening adapted to receive a bolt or set screw 21 by means of which the locking plate is secured to the saddle. The saddle is provided with a pair of vertical grooves 22, adapted to receive the edges of the locking plate and the upper edge of this plate is provided with a curved portion 23, curved on substantially the same radius as the radius of the aperture 6. As shown, the

plate 20 forms the front wall of the lubricant well 17 when the parts are assembled (see Figure 4). A bearing brass consisting of a pair of sections 24 is adapted to be arranged in the driving box in the'usual manner. The lower edge of each plate is adapted to engage the upper edge of the saddle, as shown in Figure 3 ofthe drawings, to retain them in proper position. As shown, the rear Wall of the aperture is provided with a flange 25 (see Figure 7) to prevent longitudinal displacement of the bearing brass. In Figure 6 of the drawings, I have shown a spacing member 26 which is adapted to be inserted between the two sections of the bearing brass when the bearing brass becomes worn, to spread them, and thus take up wear. In Figure 5 of the drawings, I have shown a shim or liner 27 arranged in the driving box between the wall of the aperture and the bearing brass to take up wear when the amount of wear is so great that the spacer '26 will not suiiice for this purpose. 7 I

The operation of the device will be apparent from the foregoing description. As the bearing brass wears, a spacer 26 is first inserted and a shim or liner 27 inserted upon further wear of the brass. The saddle may be adjusted upwardly by moving it toward the rear of the drivii'ig box, causing the ribs 10 to move upwardly in the tapered grooves 9. w The construction is so simple and by provldi'ng the open portion of the aperture at the bottom, the brass may be removed without dropping the wheels of the locomotive.

t is to be understood that the form of my invention herewith shown and described is'to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of V the subjoined claims. 7

I claim;

1. A locomotive drivingbox having a smooth arc'uate bearing recelving aperture,

said flanges with vertical grooves, and a plate slidable in said grooves and forming-a closure for the front portion of said saddle.

2A. locomotive driving box having a tapered bearing receiving aperture,- and having an opening beneath and communicating with said aperture, a brass formed of complementary members tapered similarly to and adapted to be received in said aperture,

and a saddle arranged in said opening. and

having portions adapted to contact with the lower edges of said brass, said driving box being provided with supporting means for said saddle.

8.1K locomotive driving box having a tapered bearing receiving aperture and having'an opening beneath and communicating with said a Jerture each of the side wallsot said opening being provided with an inclined inwardly projecting shoulder, an arcuate brass formed of a pair of complementary'rnembers tapered similarly to and adapted to be received in said aperture, the lower edges of said brass being arranged below the center of curvature thereof, a saddle arranged in said opening and having por-' tions projecting outwardly of said driving box, the lower edges of said brasses being adapted to contact with portions of said saddle, and means connected between said driving box and the projecting portions of said saddle for drawing the latter inwardly, said saddle having portions adapted to slide upon said shmilders to move said saddle upwardly as it is drawn inwardly.

4. A device constructed in accordance with claim 3 wherein the contacting portions of said brass and said saddle are arranged substantially radially oi said brassfl In testimony whereof, I affix my signature.
